iam not able to view the images in the tree

hi all

iam not able to view the images loaded in the tree

but the space for the image is allocated but can not view it

i have added a bitmap and also created the imagelist but iam not able to

view it....

CImageList m_TreeImg;
m_TreeImg.Create(IDB_BITMAP, 16, 5, RGB(255, 255, 255));
m_Tree.SetImageList(&m_TreeImg, TVSIL_NORMAL);

HTREEITEM hCompany, hOffice, hProg, hOperSys, hProd;
hCompany = m_Tree.InsertItem("Microsoft", 0, 5, TVI_ROOT);
hOperSys = m_Tree.InsertItem("Windows 9x", 5, 1, hCompany);
hOperSys = m_Tree.InsertItem("Windows NT", 5, 1, hCompany);
hOffice = m_Tree.InsertItem("Office 97", 1, 4, hCompany);

hProd = m_Tree.InsertItem("Word", 2, 3, hOffice);
hProd = m_Tree.InsertItem("Access", 2, 3, hOffice);
hProd = m_Tree.InsertItem("Excel", 2, 3, hOffice);
hProd = m_Tree.InsertItem("OutLook", 2, 3, hOffice);
hProd = m_Tree.InsertItem("PowerPoint", 2, 3, hOffice);

hProg = m_Tree.InsertItem("Visual C++", 3, 4, hCompany);
hProg = m_Tree.InsertItem("Visual Basic", 3, 4, hCompany);
hProg = m_Tree.InsertItem("Visual FoxPro", 3, 4, hCompany);
hProg = m_Tree.InsertItem("Visual Interdev", 3, 4, hCompany);


and so on....

Every thing is perfect

only thing i cannot view the images even it has allocated the space for the image b4 the text of the tree items....

This might be a silly question, but do you add images to m_TreeImg? From the code you posted, it looks like you are setting an empty image list to your tree control.

That's somewhat confusing: The prefix (m_) suggests that m_TreeImg is a member variable of a class, but the code as you posted it looks like it was a local variable... So what is it? And if it is a local variable it won't work, since the image list will be destroyed when it goes out of scope.

No, he loads the bitmaps from a resource (IDB_BITMAP).

and i have another question CMenu

the code is as follows..


void CMyDlg::OnContextMenu(CWnd* pWnd, CPoint point)
{


CMenu menu;

menu.LoadMenu (IDR_MENU2);

CMenu *pMenu=menu.GetSubMenu(0);

pMenu->TrackPopupMenu (TPM_LEFTALIGN ,point.x,point.y,pWnd);
}


if i write any actions on the menu items to handle any operations of the dialog it is not working

for eg when i rclick this menu popups how should i write code for the menu item so that i can exit or do any action for the dialog ...

You'd better start a new thread for that, since it is not related to your original question.

Anyway:

You are passing the pWnd you get in OnContextMenu to the TrackPopupMenu - that's your dialog window, and that won't work: The command routing (as required for menu command handlers) needs a frame window, not a dialog box.
